Salespeople "who sell. articles of unusual proportion or weight suchas stoves,-electric refrigerators,

sales because the prospective customer is' unable to visualize the article in its actual size in hisown home or placejof business. W hereas if'the, prospect could see a full sized representation of; the article] under consideration 7 he could'better determine if it was of suitable size, etc. i Also, with a full'sized illustration of hisproducts before his customer, the sales man can better-explain the advantages and superiority of his product. Y r

However it is "very costly and impractical toactuallytransport and installsuch articles merely for purpose of demonstration. f It is therefore an object or my which, when" setup and adjusted, presentsfa full sizedportrayal of an article. i Another Object isto provide a novelj dis- 'playdevice adapted to fold into a compact carrying case which case, when the device is *in use,forms a part of'the device; f

The size of the caseand the appurtenant devices is determined entirely by thej size 3 of the articlejit is desired to display and the" number of chart rolls desire d. It rislto'j be,

understood that the length of the rolls and the number of rolls provided in the case may be varied to suit the demandzor ;the us'ev to which the device isto be adapted withoutdeparting from the i spirit of the; invention.

'erence numerali; j 2 1 I ,1 7 The ro'llsl5 are of the window shade type j except that I provide said :rolls' with the":

longitudinal 'groove'16. ini the:periphery;there Forillustrative purposes the caseis-shown I prov ded with-two chart;roljls l5.=' The rolls;

being identical are indicatedby thesame-ref her of charts may be used with a minimum number of rolls.

It is not thought necessary to include in this specification detailed description of the construction of the spring device for the roll as it is of well known construction. '1 ie spring (not shown) is tension-ed when the chart is unrolled and the usual latch (not shown) is provided to retain the chart in its unrolled position. WVhen manually re leased, by slightly advancing theroll, the spring rotates the roll to rewind the chart thereon.

The rolls 15 are removably supported at one end of the case by a bracket 19 secured to the inside of one end wall of the case. The other end of the rolls being supported in a bracket 20, secured to the inside of the other end wall of the case. The axle (not shown) on the spring motor end of each of the rolls is inserted into an aperture (not shown) in the bracket 19 and a trunnion 21 secured to the other end of each roll is then dropped into an open slot 22 in the bracket 20. A look ing arm 23, pivoted on a stud projecting from the bracket 20, is then moved to the po ition in which it appears in Fig. 2, where it is held by a projection 24 thereon engaging a hole in the bracket 20, thus holding the rolls 15 in position in the case.

When it is desired to use the display device, the case is inverted with the lid open and a bracket or socket 26, (Figs. 8 and 5) secured to the inside rear wall of the case opposite the handle, is fitted over the upper end of a tripod stand 27 or any suitable support. I prefer, however, to use a folding tripod, because when not in use the tripod may be folded up and conveniently carried in a compartment provided in the case for that purpose. This compartment is formed by a partition 28 (Figs. 2, 3 and l) and the rear wall of the case.

When the case is mounted on its support stand or tripod 27, the lid 11 hangs downward and a bracket 29 (Figs. 3 and 5) secured to the inner side of the lid, and having a notch 30 therein embraces the tripod 2'? to brace the case against sidesway, thus insuring that the chart in use at the time will hang perpendicular to the floor. In the illustration (Fig. 1) the chart is shown only partly unrolled. It is to be understood however that the chart in actual use may be drawn downwardly to its full extent completely concealing the support or tripod. The inverted case besides forming a convenient support for the chart rolls also affords a means for completely concealing the rolls from view when the device is in use.

The lower end of the chart is formed into a loop into which is inserted a small metal rod having its ends 32 projecting beyond the chart 17 (see Fig. 1). This rod is of suiiicient weight to prevent the chart 17 from curling,

and holds the lower end thereof at the point to which it is lowered.

When the chart is rewound on its roll the rod is drawn upwardly and the ends 32 coming into contact with the brackets 19 and 20 arrest the rolling movement, otherwise the roll would rotate until its spring (not shown) was exhausted.

l/Vhile the form of mechanism herein shown and described is admirably adapted to fulfill the object primarily stated it is to be understood that it is not intended to confine the invention to the one form or embodiment herein disclosed, for it is susceptible of embodiment in various forms all coming within the scope of the claims which follow.

What is claimed is:

1. A device for carrying and displaying charts including a case; means in the case to support a. plurality of rolls, each roll having a chartwound thereon; means on the case to receive a support rod; and means on the case to cooperate with said rod to brace said case.

2. In a case for carrying and displaying charts including a lid; the combination of means secured to the inner end walls of the case to support a plurality of rolls, each roll having a chart wound thereon; means secured to the case to receive a support rod; and means on the lid .cooperating with said rod to brace the case.

3. In a case for carrying and displaying charts; the combination of means secured to the inner end walls of the case to removably support a plurality of rolls, said rolls having charts wound thereon; means to retain the rolls in the support means; and means on the case to receive a support rod whereby the case is invertedly supported to form a concealing and supporting enclosure for the rolls.

4. In a case for carrying and displaying charts; the combination of means secured to the inner end wall of the case, but spaced apart therefrom, to removably support a plurality of rolls, said rolls having charts wound thereon; pivoted means to retain the rolls in the support case; and means in the case to receive a support rod to invertedly support the case to form a concealing and supporting enclosure for the rolls.

5. In a case for carrying and displaying charts including a lid; the combination of brackets secured to the inner end wall of the case, but spaced apart therefrom, to removably support a plurality of rolls, said rolls having charts wound thereon; means pivoted on one of the brackets to retain the rolls in the support means; means secured to the case to receive the support rod to invertedly support the case; and means on the lid to cooperate with the support rod, when the lid is open, to brace said case.

6. In a case for carrying and displaying charts including a lid; the combination of i I brackets secured to the inner end walls of the case, but spaced apart therefrom; a plurality or'rolls removably supported by the brackets, each roll having a chart woundthereon; a locking'arm to retain all of the rolls in position; a socket secured to aninner wall of the caseto receive a support rod to invertedly support the case; and a bracket on the lid to embrace the support rod to prevent'rocking movement of the case. a

7. In a case for carrying and displaying charts including a lid; the combination of brackets secured to the inner end walls of the case said brackets being provided with suitable apertures to receive a plurality of rolls; 'a locking, arm pivoted on one of the brackets to retain the rolls in position; -a' socket secured 'to'theinner wall of the case i to receive a support rod to invertedly support the case, whereby the casev forms a concealing andsupporting enclosure for the'rolls when the charts are being displayed; and a-bracket on the inner side of the lidto cooperatewith the support rod to brace the case.

In testimony whereof I aifix my signature.
